car problems.. help me understand?

[x99suplarax]

ok.. i havent done it yet.. and hopefully itts the only problem.. i just looked at my previous spark plugs(ngk gpower) and the ones that i have now(ngk laser platinum).. and they werent gapped at .044..

also my cousins husband had posponed to do the compression check.. now i gotta go through a shop or a friend if he isnt busy..

also again if i accidently forgot to put a connection back on the ecu then connect the battery and start the car.. could it hurt anytyhing? like fuses,wires, ecu?

I wouldn't think that leaving a wire disconnected would hurt anything, unless it shorted out. So check all your fuses to make sure they are good. I think if a wire was off of the ECU the car probably wouldn't start at all. If the gapping is wrong the plug won't operate as intended.
